I think lmbench, bonnie++ and AIM-suite9 are not suitable when you compare l4/fiasco with ecos although they are real-time operating systems. L4 itself is not linux binary compatible but l4linux could provide full linux binary comptability. And these benchmark tools must run on the linux-binary-compatible system such as BSD,UNIX, etc. So we could compare l4linux with linux by using lmbench, bonnie++ and AIM-suite9. Although ecos could provide many linux APIs but it is still not linux binary compatible. In common we can't compile these tools on the ecos so the benchmark is impossible. Additonal lmbench, bonnie++ and AIM-suite9 are designed for the general purpose operating system. From the result we could know the average performance of the system. Therefore, if you want to compare l4 with ecos you could take these two system as real-time systems and you should get some data showing real-time performance such as jitter, responsing time, etc. But there is no benchmark tool which could cover these two platforms : l4 and ecos. So you have to write your application for this goal. Thanks Cheng Guanghui

In this paper I use lmbench, bonnie++ and AIM-suite9. But I don't use lmbench, bonnie++ and AIM-suite9 to test the Fiasco itself but test the the performace loss between l4linux-2.6.16 and linux-2.6.16. In this benchmark I login into l4linux with a console because in this way we could ignore the effection of graphic interface for performance loss. It is not complex but only a confiugration problem. If you want to login l4linux with console you could use the configuration file like this: modpath "(hd0,2)/boot/L4Linux" task "vmlinuz26" "earlyprintk=yes console=ttyS1,115200 init=3 mem=256M" root=/dev/hda3" all_sects_writable Is this clear?
